NVD Description

Note: Versions mentioned in the description apply only to the upstream e2fsprogs package and not the e2fsprogs package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

A code execution vulnerability exists in the directory rehashing functionality of E2fsprogs e2fsck 1.45.4. A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability.
